branes of dorsal between seventh to twelfth rays spotted with 

 reddish-brown and spots increasing in size, numljer, brightness and 

 irregularity of outline from front to rear." 

 Five examples. 



COTTIDiE. 



OncOOOttUS hezaoornis (Richardson). 



In all six examples, largest 9 inches long. They all appear to differ 

 in the aggregate of characters from the form which I shall indicate 

 as Oncocottus hexacornis gilberti. They are apparently all much broader 

 than in the latter, the preopercular spines are all comparatively 

 shorter, the coloration darker, the cranial osseus excrescences usually 

 not so highly developed , and certain sexual characters are apparently 

 well marked. A small male about 6 inches in length shows the 

 membranes between the dorsal rays deeply scalloped, thus resem- 

 bling Dr. Scofield's figure.'' This fin, however, is more spotted or 

 blotched with white. There are also two very distinct white trans- 

 verse bands on the caudal, though a little further out from the base 

 than his figure shows. In other respects, such as the small cranial 

 protuberances and more pronounced markings on the pectoral, at 

 least five transverse blackish bands. The more distinct color mark- 

 ings seem to be a character of small or young examples. The larger 

 examples are females and agree better with most figures. They have 

 the second dorsal entire. All from Point Barrow, one was found 

 chilled on the beach August 29, 1897.

Body depressed, elongate, but more slender when viewed from

 posterior angle of preopercle. Caudal peduncle slender, its least
